3.7 CMA Replacement
Note:
The standard CMA has two arms, labeled "upper" and "lower." The lower
arm should have the elbow on the left side and be installed first; the upper arm
should have the elbow on the right side and be installed last.
Note:
CMA Lite has one arm, to be installed at the lower position. This arm should
have the elbow on the left side.
a.
Orient the CMA so that the elbow is on the left hand side.
b.
Attach all three of the connectors to the brackets on the rails. There should be one at the
elbow side and two at the other end.

c.
Slowly slide the enclosure forward to ensure the arm is operating properly, then slide it back
into the rack.
d. CMA Standard:
Repeat these steps to install the upper arm with the elbow facing to the
right.
Step 15 :
Cable the CMA(s).
CMA Standard:
a.
Unlatch the elbow side of the arm(s) by pressing the blue button labeled “push,” and then
swing the arm(s) open.
b.
Gather the SAS, power, and Ethernet cables for installation. Before cabling, note the
following routing patterns for best results:
Note:
Route the cables supported by the lower arm to IOM A (left hand side
looking at the rear). Second, route the cables supported by the upper arm to
IOM B (right hand side looking at the rear) in a "criss-cross" pattern. See the
Special Considerations for Cable Routing
for more information.
